Yeah, well...German is not exactly the language one would want to learn, i guess ^^....
Okay, so, here´s the log and besides that everything is like it was before...
Did you see the screenshots i posted quite at the beginning? With all the letters and words being replaced by squares?
That´s the problem basically....there´s no problem running the internet (words, letters, symbols...everything´s fine there) or any other programme like vlc media player etc.
Only got the trouble with Microsoft Office (and avast) and the whole administration...all nice squares instead of letters there :/
Seems like it´s a problem with the operating system...?!
There are system-updates waiting there, but i only get the error code that there was a problem installing them...
Could that be the source of all that trouble?
